Abstract

  The present invention is a vehicle fan device, wherein the fan device has a control device and a motor for operating a ventilation device of the fan device. The fan device is formed so as to be cooled through a common air flow of the ventilation device.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fan device for connecting to air conditioning equipment or fan equipment provided in a vehicle, for example, an automobile.

  Usually, it is necessary to supply sufficient air for internal cooling to the motor of the fan device. This cooling air is generally supplied via an air passage, which forms a connection between the motor casing and the customer-side fan or air conditioning equipment.

  Furthermore, it is necessary to cool the control device for controlling the fan device of the vehicle. For this purpose, the cooling device of the control device is generally inserted into the wall of the fan casing of the fan device, where the cooling device is located directly in the tangential air flow of the fan. Alternatively, the control device may be arranged in the immediate vicinity or underneath the fan device ventilator so that the cooling body is located in the radial air flow of the ventilator.

  Thus, in accordance with the present invention, a fan device with improved cooling of the control device and motor is provided.

  A fan device for a vehicle in particular according to the present invention has a control device and a motor for operating a ventilation device of the fan device, and the motor and the control device have a common air flow. The fan device is formed so that it can be cooled via the fan device.

  Such a fan device has the advantage that it is not necessary to take separate measures or to provide a separate interface in order to properly cool the control device and the motor.

  This can reduce manufacturing costs and assembly costs. Furthermore, adaptation to the customer's fan equipment or air conditioning equipment is significantly simplified. The fan device according to the invention further provides a module in which the cooling of the motor and the control device is already integrated.

  Further advantageous configurations are set forth in the dependent claims.

  In one configuration according to the invention, the control device is arranged behind or below the ventilator. This has the advantage that the control device has no risk of negatively affecting the air flow created by the ventilation device.

  In another configuration according to the invention, the fan device has an air passage guide in which part of the air flow of the ventilator is guided along the control device and continues towards the motor. Will be guided. This has the advantage that both the control device and the motor can be cooled by a part of the air flow of the ventilator. In this case, as the air flow, a part of the air flow flowing out from the ventilation device in the radial direction is used, and this air flow then flows toward the control device.

  In yet another configuration according to the present invention, the air passage guide (or the casing of the fan device in which the motor and the ventilation device are also arranged) has a partition member, and the partition member removes the control device from the ventilation device. While separating substantially in the axial direction, the partition member opens the casing of the air passage guide or fan device to the control device in a substantially radial direction. Said axial isolation has the advantage that the control device has no negative influence on the air flow of the ventilator. However, the air passage guide part or the casing of the fan device, in at least one section in the radial direction, does not isolate the control device from the ventilation device, but opens this region, so that it flows out, for example, in a substantially tangential direction. A part of the air flow of the ventilator can be used to cool the control device and additionally the motor.

  In the following, embodiments of the invention will be described in detail with reference to the drawings.

  In all drawings, the same or the same function members and devices are denoted by the same reference numerals unless otherwise described.

  First, FIG. 1 shows a perspective view of a fan device 10 based on the prior art. In this case, the fan device 10 has a ventilator 12, which sucks air from the surrounding environment, and further, for example, via a correspondingly arranged fan casing device 14, the vehicle air conditioning equipment or fan equipment I will guide you to. The casing device of the air conditioning equipment for guiding the air flow, for example, to which the fan device 10 can be connected, is not shown for the purpose of making FIG. 1 easier to see. Furthermore, a motor 16 for operating the ventilation measure 12 is provided. In this case, the motor 16 can be controlled via an external control device, for example as shown in FIG. 3 below, or alternatively in the form of a switch provided in the vehicle, for example. Can be controlled via a simple actuator.

  FIG. 2 is a perspective view of another fan device 10. In this case, the fan device 10 also has a ventilation device 12. The ventilator 12 draws air from the surrounding environment, and then the air flow enters the fan casing device 14 from the ventilator 12 in the radial direction. The fan casing device 14 further guides the air flow to an air conditioning facility or a fan facility (not shown) connected to the fan device 10. For this purpose, the fan casing device 14 has a fixed flange section 18 at one end. In this case, the motor 16 for actuating the ventilation device 12 is actuated via, for example, a suitable actuating device, for example in the form of one or more switches provided in a correspondingly arranged vehicle. For example, a control device for precisely controlling the motor 16 is not provided in this embodiment.

  Further, FIG. 3 shows a perspective view of the fan casing device 14 of the air conditioning equipment or the fan equipment for connection to a fan equipment (not shown) of the air conditioning equipment, for example. In this case, a fan as shown in FIG. 1 may be used as the fan device. In this case, an external control device 20 is provided, and this control device 20 is arranged in the ventilation device 12 of the air conditioning equipment at a separate control device position. In this case, the control device 20 is cooled by the air flow, and this air flow flows out from the ventilation device of the fan device toward the connected air conditioning equipment or fan equipment.

  FIG. 4 shows another perspective view of the fan device 10 based on the prior art. In this case, the fan casing device connected to the fan device 10 is not shown for the purpose of making the drawing easier to see. As can be seen from FIG. 4, a control device 20 for controlling the motor 16 of the ventilation device 12 is provided below the ventilation device 12 or the bucket ring 22. In this case, the control device 20 has a surface provided with a plurality of projections such as aluminum projections on one side as the cooling body device 24, and the control device 20 is cooled via these projections. Can do. In this case, the control device 20, together with its cooling body device 24, is located in the radial air flow of the ventilation device 12.

  FIG. 5 shows a view of the fan device 10 shown in FIG. 4 as viewed from the motor 16 side. Below the protruding surface of the cooling body device 24, an electronic device 26 of the control device 20 and a connection connector 28 for the control device 20, for example, are provided.

  Conventional embodiments of the fan device have various drawbacks. That is, an interface for supplying air, for example, cooling air, to the air conditioning equipment or fan equipment of the vehicle must be defined and supplied between the fan device and the air conditioning equipment or fan equipment of the vehicle.

  Furthermore, the interface generally requires different structures for CW (clockwise) motors and CCW (counterclockwise) motors. The shape and dimensions of the interface must be carefully adjusted between the customer and the supplier. Every air conditioning equipment or every custom fan device installed in a vehicle requires a separate structure. In addition, the cooling performance is highly dependent on where in the custom fan device the air outlet (Luftangriff) is located. Quality cannot be assessed unless assembled with a custom fan. However, such an interface has potential weaknesses, for example, with respect to sealability and manufacturing errors, and requires great effort with respect to structure and manufacturing.

  When the control device is arranged at an arbitrary position in the fan casing of the fan device, the same disadvantages as in the case of the air take-out portion for cooling the motor occur in the heat removal design of the control device. That is, the control device is not optimally cooled, for example, or the control device is based on its built-in position, resulting in an unfavorable disturbance in the air flow of the ventilator.

  Furthermore, in such an embodiment of the fan device, the ventilation device consists of two separate groups. In this case, when the control device is placed in the radial airflow of the ventilation device and on the module support of the fan device, the cooling body is located sufficiently in the airflow to cool the control device, on the one hand. On the other hand, it is necessary to configure the control device so that it can be accommodated in a limited configuration space. This generally results in a complex and cumbersome configuration, particularly with respect to the special shape of the ventilator. Furthermore, the cooling body of the control device entering the radial air flow of the ventilation device causes an obstruction of the air flow. This also causes a decrease in fan performance.

  Thus, in accordance with the present invention, an improved fan device 10 with an incorporated control device 20 is provided.

  FIG. 6 is a perspective view of the fan device 10 according to the embodiment of the present invention as viewed from the direction of the motor 16 of the fan device 10. In this case, the fan device 10 is coupled to a fan casing device 14 which is arranged, for example, almost completely around the ventilation device. The fan casing device 14 may be coupled to the fan device 10 as a separate part or may be part of the fan device 10.

  In this case, in order to fix the control apparatus 20, the accommodating part 32 is arrange | positioned under the ventilation apparatus in the casing division. In this embodiment, an air flow is sucked in by the ventilator and a part of this air flow is then guided along the control device 20 towards the motor 16, so that the motor 16 is also cooled, for example.

  In FIG. 7, only the fan device 10 is shown without a fan casing device that can be coupled to the fan device 10. In this case, the fan device 10 viewed from the direction of the inlet of the ventilation device 12 is shown. In this case, the control device 20 is disposed in the housing portion 32 provided in the casing or the casing section 30 below the ventilation device 12. In this case, the control device 20 is closed or isolated with respect to the ventilation device 12 when viewed in the axial direction. This is achieved by providing the partition member 34 between the control device 20 and the ventilation device 12. In this case, the ventilation device 12 is formed to be open to the control device 20 in the radial direction.

  For this purpose, the partition member 34 has, for example, at least one opening 36 in the radial direction or substantially in the radial direction. In this way, a part of the air flow of the ventilation device 12 flows toward the control device 20 or the cooling device 24 of the control device 20 without the air flow of the ventilation device 12 being obstructed by the control device 20. Is achieved. In this case, the control device 20 has, for example, one surface including a plurality of projections 38 such as aluminum projections as the cooling body device 24, and the projections 38 can be cooled by the air flow of the ventilation device 12. It is. However, any other type of cooling device 24 can be used. What is shown in FIG. 7 is purely an example. In particular, the electronic device 26 of the control device 20 may be provided below the cooling device 24.

  FIG. 8 shows the fan device 10 according to the present invention, the outer fan casing device 14 coupled to the fan device 10, and the control device 20 in the housing portion 32 in a partially sectional view. . In this case, the control device 20 has, for example, a connection connector device 28 in addition to the electronic device 26 below the cooling body device 24. Furthermore, the accommodating part 32 by which the control apparatus 20 is arrange | positioned inside is closed with the corresponding partition member 34 with respect to the ventilation apparatus 12 by the axial direction. Thereby, the 1st air passage section 40 in which the ventilator 12 is arrange | positioned, and the 2nd air passage section 42 in which the control apparatus 20 is arrange | positioned on it are formed. In this case, since the accommodating portion 32 is formed so as to be opened in the radial direction, the accommodating portion 32 can be flowed together with the control device 20 by, for example, the air of the ventilation device 12 flowing out in the tangential direction. In other words, this provides a kind of underfloor ventilation in order to properly cool the control device 20 without obstructing the air flow of the ventilation device 12. In this case, since both air passage sections 40, 42 are connected to each other in the radial direction, a part of the air flow of the ventilator 12 can flow towards the control device 20 and then towards the motor 16.

  As shown in the sectional view of the fan device 10 in FIG. 9, the control device 20 is incorporated in the housing portion 32 so that the cooling device 24 of the control device is positioned in a tangential or substantially tangential air flow. It is. Further, since the housing portion 32 is connected to the inner chamber of the motor casing via the second air passage section 42, a part of the air flow of the ventilation device 12 can be taken out and supplied to the motor 16 at the same time. Thereby, the motor 16 is cooled, for example.

  As shown in FIG. 9, the air passage guide portion is configured by arranging two portions substantially symmetrically. In this case, as indicated by arrows in FIG. 9, air is first sucked through the ventilator 12. The air flow then exits ventilator 12 in the radial direction. In this case, a part of the air flow, for example the majority, flows into the first air passage section 40 and from there further flows into the connected outer fan casing device 14. The fan casing device 14 supplies an air flow to, for example, a connected air conditioning facility or fan facility. The air flow exiting another part of the air flow or substantially tangentially flows into the second passage section 42 of the fan device 10. This is because the accommodating portion 32 is closed only in the axial direction with respect to the ventilation device 12 by the partition wall member 34 and is not closed in the radial direction. That is, the air flow follows the ventilation device 12, for example, through the opening 36 toward the housing 32, or along the control device 20 and its cooling device 24, and finally with the motor 16, for example, It flows toward the carbon brush of the motor 16. Thus, both the control device 20 and the motor 16 can be appropriately cooled without hindering the air guidance of the ventilation device 12.

  For this purpose, the ventilator 12 is axially isolated from the control device 20 by the partition member 34 as described above, so that the air flow through the first and second passage sections 40, 42 is mutually negative. There is no fear of affecting each other. In this embodiment, the partition member 34 is formed with a conical base 44, for example, as shown in FIG. However, as long as air guidance is provided along the control device 20 toward the motor 16, it may have a flat or flat base, or any other shape as well. In addition to the base 44, the partition member 34 additionally has a side wall section 46, for example, which forms part of the second air passage section 42 and this second air path section. 42 is at least partially isolated from the fan casing device 14 that supplies air from the ventilator 12 to, for example, air conditioning equipment.

  As explained above, a part of the air flow of the ventilator 12 flows towards the control device 20 and then flows outwardly in the direction of the motor 16 via the second air passage section 42. Another part of the air flow of the ventilator 12 or, in this embodiment, a large part flows radially outwardly via the first air passage section 40 and from there for example a connected vehicle air conditioning or fan installation. Flow into.

  FIG. 10 shows another sectional view of the fan device 10 according to the present invention. In this case, a fan casing device connectable to the fan device 10 is not shown. The control device 20 provided in the housing portion 32 includes, for example, a connection connector 28 in addition to the cooling body device 24 and the electronic device 26. Furthermore, for example, a side wall member 46 that partially surrounds the circumferential direction of the partition wall member 34 and a conical base 44 are shown. Further, as shown in FIG. 9, the flow of air flow from the ventilation device 12 to the control device 20 and the motor 16 is shown along the air passage sections 40 and 42 by arrows.

  In the present invention, the heat removal of the control device and the motor cooling are integrated into one common structure, so that they do not have to be realized separately from each other. Furthermore, the structure is fully integrated into the fan module or fan device. The present invention has the advantage that in this case no special interface to the custom air-conditioning or fan equipment is required anymore for taking out the cooling air for the motor and the control device. This makes the built-in interface for ordering significantly easier and more robust.

  Another advantage of the fan device according to the invention is that the positioning of the underfloor ventilation can be defined on the peripheral surface of the fan device independently of the custom air conditioning facility or the custom fan facility. The configuration is largely independent of the order design. The number of custom versions is reduced. Furthermore, the cooling performance for motors and controllers is not significantly dependent on custom design and can be generally optimized without custom fan equipment. Based on a substantially symmetrical configuration, this configuration can be used for CW fans and CCW fans as well. This further reduces the number of required individual parts significantly. The underfloor ventilation structure also provides sufficient space for the standard controller. There is no need to use a specially adapted, complex cooling device. Due to the overcoating on the ventilator by the septum member, the radial air flow continues to be interrupted and unimpeded. Furthermore, it has been found that underfloor ventilation is relatively robust with respect to various receptacle cross sections and various fan casing device cross sections. Through the configuration and arrangement of the individual cross sections, the volume flow of the cooling air flow can additionally be optimized.

  In this case, as shown in FIG. 7, the fan device can be delivered as a fan module, which can later be connected to the fan casing device of the air conditioning equipment on the customer side, for example. However, for example, as shown in FIG. 6, the fan device may additionally have a dedicated fan casing device, and can be connected to a customer-side air conditioning facility or fan facility via a corresponding interface. In this case, as shown in FIG. 6, the fan casing device has, for example, a section that is expanded radially and / or axially at the end. In this case, this end section of the fan casing device may additionally be formed as an interface for connection to a vehicle, for example an air conditioning facility or a fan facility of an automobile.
